If you do it right, you can run the single RPM lead back into the motherboard 3pin so the RPM's are still monitored. If the cooling is OK and it is just a noise problem, then a cheap fix is to use the +5 volt instead of the normal +12 volt by re-wiring a 4pin - 3pin adapter. This is the one I bought thermaltake but any HSF with 4 or more heat pipes and a large fan would work. I had to pull the mombo out but it was worth it. I decided it was cheaper to put in a good HSF then replace the CPU. I spent an hour looking around at various HSF devices before spending a bunch for a good one. Not only was it fairly loud, it was not cooling when all 4 cores were busy. I had a similar problem with a Q6700 stock intel fan. Please help! Or I will be stuck crunching at a rate slower than my old CPU! I was recommended to SpeedFan and I cannot seem to figure out how to make it work seems to have done nothing for the machine. Smart-Fan control for managing fan speed control of both CPU cooling fan and North-Bridge Chipset cooling fan. How can I make my fan run a constant, lower speed? I am trying to get the most out of this processor but under windows XP the fan is uncontrollably loud when I try to run BOINC over 30% usage.100% sounds like your average hurricane. Awhile back I bought a stock computer (blah) a Gateway GT5662 with an AMD Pheonom 9500 Quad-Core processor.
